Biology
1 answer:
matrenka [14]3 years ago

PLEASE HELP!! “Place the events of the construction of proteins in the correct order.”
Alik [6]

Answer:

The correct order of events of protein synthesis would be from the properties of DNA to forming of polypeptide chain. The correct order would then be B, A, E, D, C.

The following are the correct order of events of translating genetic information on a DNA:

transcription: information of a DNA is transcribed into mRNA in the nucleus.

the mRNA is moved from the nucleus to the ribosome.

amino acids attached to tRNAs are also moved to the ribosome.

the message on the mRNA is translated with the tRNA dropping the amino acid corresponding to the codons on the mRNA and individual amino acids are joined by polypeptide bonds.

HELP!!!!! NEED A CLEAR ANSWER ASAP PLZ!!!!
ValentinkaMS [17]

Answer:

Hormone levels are changing during menstruation and ovulation. The general trend of hormones after ovulation -when an individual approaches menstruation- is that hormone levels generally decrease.

Explanation:

In a woman's menstrual cycle, hormone levels tend to increase or decrease according to reproductive requirements. On the days close to ovulation, the hormones must prepare for the release of an egg and the preparation of the female reproductive organs for the possibility of an embryo.

If fertilization of the egg does not occur, hormone levels generally tend to decrease until menstruation occurs.

In the attached graph (picture) the behaviour of hormones in an adult woman can be clearly seen, where estradiol, follicle-stimulating hormone, progesterone and luteinizing<u> hormone tend to decrease their levels at the end of the luteal phase, in the proximity of menstruation</u>.
